So, I want Del in my town so I invited him via Amiibo, I did his 3 chores for 3 days, and he's ready to move in, he asks resident services, and says that I already have 10 campers. And that's it. He doesn't do the thing where he tries to convince someone else to move out. I've talked to him over 20 times, and I'm on the 5th day of having him as a camper now, each day where he's ready to move in, he says my island's full and nothing more. Is this feature not guarenteed? What could be the cause of this? Has anybody else ran into this issue?
